Ok, I've done these "How-To" type tutorials before but I didn't really do it specifically for Marshall basketweave, aka salt & pepper, cloth before. There are a few simple tricks you need to do to get straight cloth installed on any baffle board.

Tools needed:
1) Good stapler. I use a Stanley sharpshooter, with the 8mm wide, 5/16" deep staples. Get it at any Home Depot for under $30 including a ton of staples.
2) 1/4" wide straight tip screwdriver. You'll need this to pry out any staples which didn't go in straight or only one prong made it in, or some other mistake.
3) Fairly good eyesight, or good glasses (you decide!).
4) Strong hands to pull the cloth. The basketweave cloth is thicker than most others and requires you to pull hard on it to get it flat and tight.
5) Patience... otherwise you'll f**k up a $60 piece of grill cloth and you'll be more pissed than if you were patient and paid attention to this tutorial. I've been there and wasted cloth, so this isn't a slam. Follow my instructions here and you can have great looking cloth on your cab in about 45 minutes. Yep, 45 minutes. I clocked this from start to finish on a 2x12 cab and it took me 35 minutes. Since a 4x12 cab is only 8 inches taller than a 2x12, another 10 minutes is about right to shoot in the extra staples and stretch the cloth.

Ready?

1) First cut the bw cloth about 4-6 inches larger than your baffle board. On a full width Marshall 4x12 cloth that's going to be around 34-36 inches wide. Cut the cloth so that the black & white threads run up & down the long way. Cut it as close to one particular thread as possible without crossing over to other threads. It's important to not waste any extra cloth and it makes step #2 easier as well.

2) Pick out a specific thread that's about 3/4 inch in from the cut cloth edge that's the long thread running vertical. You're going to fold along that one specific thread the entire height of the cloth. This is the thread I'm talking about, it's the right side of the baffle board as you face the cab (looking down from top to bottom). You'll fold it completely over in a 180 degree (U-turn) fold. The establishes the crease you'll want and the flat edge to push into the baffle board edge when stapling.

3) Now you'll want to pick out a thread to go along the top edge of the baffle board. I usually pick the black ones that appear darker/thicker. Since the thread is longer from top to bottom, it looks wider when viewed from left to right.

Here's where I bend it, again in a full 180 degree U-turn, then lay it on the top edge of the cab to check the thread to see if it lays down right. Keep in mind, this cloth is not EXACT. It waves a bit. You'll have to do this crease really well for straight cloth so don't sluff off and get lazy. Here's how I sight it down the top edge, for reference.

You'll have a corner that looks like this when ready to staple.

4) Staple the cloth to the baffle board. Make sure you keep shoving the folded edge into the baffle board corner to keep it straight. I staple at a 45 degree angle and I try to get the staples spaced evenly from each other, and in the middle of the baffle board side to minimize pull, and distortion of the cloth.

Put extra staples in at the corners to keep them anchored and straight, as you'll be pulling on them at the far corners after picking out a thread to line up and staple.

5) At this point you should have your top and right sides stapled flat and straight. The real muscle portion starts now. Sight a thread down the left side of your baffle board from the top left corner. You can't fold it, so you'll have to pull it to that thread tight down the entire left side. Staple down 2 inches from the top.

6) Sight a thread on the lower right side of the baffle board bottom (where you should have stapled down to already on the right side in part 4) then pull the cloth from top to bottom on the left side to that exact same thread. This establishes your bottom thread for pulling to all across the bottom. Fun ain't it? Staple 2 inches of cloth, then pull the other corner down tight and staple it two inches. Then pull the middle portions of the cloth on the left side tight and staple, then the middle of the bottom edge and staple.

Your fingers should be aching from using thumb and forefinger leverage to pull this tight. If they're not, then you're going to have some lumpy cloth, and you'll have to pull the staples out and stretch it again.

Here's what your bottom edge should look like when pulled tight and stapled down.

7) Check your cloth to see how tight it is. You should be able to bounce a quarter off of it about 2-3 inches in the air if dropped on the cloth from a foot up. If not, stretch it again.

When you're done, install your baffle board to your cab. Here's how mine came out on a full width (29.5 inches wide, 20 inch tall) 2x12 cab.

I can't begin to imagine the amount of profanity I'd be screaming if I did that job. Looks frustrating...

I got those two 70 Marshall cabs done today. The fabric is a real bear. The slant had particle board back and the flat had a plywood. These were bought as a pair brand new by the recent seller he even had the original cardboard box's they came in. What pain in the buttocks with his swap to SRO speakers. Did you know that those old speakers didn't have the same hole pattern as Celestions? The speakers will not bolt up to the original holes you have to drill new holes or elongate the holes in the speaker frames. I need to get the owner to spring for a set of Scumbacks. ;)

Here is a picture of the 1970 cabs I finished putting new grill cloth on. Near mint too bad they are modded.

Not my choice for speakers very bright and stupid heavy, any Scumback blows them away.

Those cabs look great, but I can't imagine how heavy they must be with those speakers...130 pounds each? Nice work on the grill cloth recover, though!

You can also spray the mounted grill cloth with water. This shrinks it, and tightens it up.

Hi Jim yes they are stupid heavy. My son and I could just barely get them stacked for the picture. I had both vinyl covers I forgot to get pictures of those and the owner is still trying to get the original boxes the seller claimed he had.

Hi Joe if you spray them do they bleed right away? The cloth always seems to have water marks it seems really susceptible to water damage bleeding. Now that's a good thing in my book as those cabs look too darn new nobody would believe they are from 1970.

I did not have any issues with bleeding.

You do got to get it pretty wet, so you should remove the speakers first. Also needs to dry overnight, or maybe hit with a hair dryer or heat gun (caution: can burn very quickly if you don't keep it moving).

I have a sad story. I pulled my 3 1972 marshall cabinets out. They have been sitting in the basement for 12-15 years. The grill cloth(large check) is falling apart. Some of the speakers will need reconed. The cones feel soft. All I can find is 32" wide large check grill cloth. Two of the cabinets are 4x12's and the other is a 4x15. I need wider large check for that cab.
Help!!!!

The baffle board is 28 inches wide so 2 inches on each side should be plenty for staples.

Jim,
I'm FINALLY getting around to putting that cloth on this old BW cab....your tutorial will be invaluable, but I have a strange feeling I won't get it right the first time around.....:facepalm

I've read it, gonna read it again.......maybe a third time, then I'll get to it!

THEN........I'll need a quad of those M75's to go in it!

I might give you a call if I get stuck.......:confused:

Thanks again Jim- you are always a HUGE help!!

Lemme see if I got this right... I restored your 69 small box head cab, then I sent you the S&P cloth, and three times through it you might still have to call me? :eek:

I'm afraid that falls under the "I'm still pissed you saw Zep 15 months ago and didn't call me to get a ticket to go..." category. I suppose with enough ridiculous bribery/groveling/internet butt cheek smooching I might answer the phone...but mister, you are starting to skate on thin ice with this one!

(Just effing with you...call if you need to.)

How's about if I threaten to buy me a quad of them there Scumback speakers?!?!?! Would THAT get ya to answer the phone??? He he he....
I do need a quad that will stand up to a 100 watter- whatchya got?? I probably missed that sale too, didn't I??

Jim, Mott the Hoople is doing a reunion in London in October.......hint hint....(the wife WILL kill me if I go back to the UK without her, but she can tag along, right??)

I don't respond well to bribes, mister...oh...wait...yes I do. :D

Not going to London for Mott since my wife won't let me, sorry.

Go start putting your cloth on so I can bust your chops about it already, would ya? And yeah you missed the sale (again!), but I may take pity on you for a quad sale...

Question.. I'm doing basket weave on a combo cab with white piping. Will staple the piping to the baffle. How much clearance on each side is needed on the baffle? I did search, and saw a "1/4 inch" mentioned in another thread, but I wasn't sure in context if the poster meant total (1/8 per side- or a 1/4 inch total less overall width (likewise for length)). I'm pretty sure it means 1/8 on all 4 sides, but want to be certain.

Hope this makes sense, goal is to measure twice, cut once.

Thanks

As of july 2012 , where does anyone recommend getting the old style large check grill cloth ? A friend got some [ don't recall where ] was a good deal 12.00 / yrd but it's
slightly tan than grey [ maybe that's more authentic ? ] but this stuff smells like fish
and i may have cut my piece too small now .
tia any replies to gboboski at gmail dot com is appreciated

I just happened to be reading this thread again and read your post. I bought cheaper stuff to save money and did not like it at all. The thread patterns were uneven and it looked terrible on the cabinets. I ended up buying from mojotone. It's good stuff, easy to work with and all in all looks perfect. It's 35 bucks a yard. It's top notch through, I love it. No fish smell either.
