Searched for this topic several ways, but couldn't get an answer. I know it's in this section, but couldn't find it.

The old cloth is easy to remove just by pulling. So, how do you put new grille cloth on the wood panel that the old cloth is glued to? What type of glue? Any specific technique to make cloth tight-fitting?

Thanks.

Maurice

I found this information on a website that sells replica grill cloth. I used followed this on my Philco 610 and it came out pretty good. The Philco has what looks like a stiff cardboard that the cloth is glued on. I just used regular old Loctite Spray Adhesive that I picked up a Walmart.

Moisture may not work as synthetic cloths don't stretch with it ...

Here are some pics of how I now do it to a baffle board:

In the first pic the ironed cloth has been held, face down, with small pieces of masking tape to a clean and splinter free board. I start on the LH side and work the cloth out from top to bottom, getting it taut. It helps that the cloth is meant for the purpose and not for covering sofas :) .

Then repeat for the RH side and now stretching horizontally as well. Then check and check and ... with a straight edge that the pattern and weft and warp are straight. If not then lift the tape only from the board , reposition and add more tape if needed. When really happy you can run a length of tape down both sides.

Now mask off the baffle and spray with the suggested adhesive and allow to become tacky. Then place carefully in position and weight down. I spray more than the 1" edge but never near the speaker or other cut outs.

If your board has holes in it, to go on the speaker studs, the best way is to heat the blunt end an old drill bit of the right size. Hold the fluke ends in moles grips and heat with a blow lamp until about cherry red. Then with the board up to the light, you can see the holes in the board and just touch the end, in the right places, to get holes that wont pull a thread when you install it.

Works for me GL Gary

Hi GL,

I'm glad you told me to skip the moistening part because I figured the grille cloth was synthetic and not cotton.

Now, where c an I get some bricks...? (just kidding)

Thanks for your very precise directions.

Best,
Maurice

If you have some old cloth Moe (piece from a polyester shirt say) its worth having a practice with a piece of scrap panel, or if you have excess of the real cloth then just go for it.

As to adhesive I use 3M "Display Mount". How much to put on?: its another of those feel things like much of re-finishing. I spray, with the panel on newspaper, both ways to get a consistent coat. Then leave to go from wet to a little tacky (back of a finger) before removing the masking tape around cut outs and placing in position.

Once in the radio the cloth comes out taut over the cut out (s), if stretched right, with spring when just gently pushed. It isn't drum tight but doesn't need to be.

It to me is a good method as the panel isn't put on the cloth until you are certain that any lines and pattern are dead straight. We see a lot of radio pictures where they aren't. Its a funny thing but images really show this up, actually more than possibly looking at the real thing.

Here's a pic of one done recently that shows excellent straight lines:

Gary,

Wonderful, wonderful work. The patterns are absolutely straight. I'll do a couple of dry runs to get the technique correct. Interesting that photos show alignment inaccuracies better than by eye.

I am fortunate my baffle is just 10" X 4".

Thanks again.

--Maurice
