The Framers Forum

It depends up on how hard the oak is, but there is a limit to how far you can expect any underpinner to successfully penetrate in to real oak. How deep are the oak mouldings that you wish to join? Oak veneered mouldings with a softer type of wood inside arequite popular with some framers. I don't us...

You sat that you are not doing shed loads of frames, so do you really need a pmeumatic underpiiner? I don't know how much space you have, but that compressor has to go somewhere and if you are a little limited for space that not only may not help, the mains cable and the compressed air hose have to ...

Having searched the internet, I can't find PLM, so perhaps the manufacturer has gone out of business. If this is so, you may need to grab whatever you can while there is stock left. Most contract framers, used to only stock 7mm and 10mm wedges, this maybe because many earlier underpinners only used ...

Lion sell them. For some strange reason in 15mm, 12mm, 7mm and 4mm. If you are wanting 10mm which is probably the most size for most jobs, Lion don't appear to list it on their wabsite, which seems a bit odd. Maybe they are letting their stock run down, before phasing them out. There can't be many o...

There are a few exceptions with some older underpinners, which can last almost indeffinately, but most people prefer newer machines. Euro underpinners are pretty much built to last forever and any wear on the manual euro in the pivoting top clamp arm does not actually matter, because you adjust the ...

I would still go for a CS-88 and if you can, I would wait until a nice one comes along. Have you phoned around some of the smaller framing suppliers to see if they have one in stock? Might be worth phoning around to see what's available. Another thought would be Mark from Underpinner Spares. Make it...

I won't be able to afford one for a little while, so I won't be wanting one just yet, but thanks for the heads up.

I think that you need to consider the build standard. Underpinners that are aimed at the entry level in the market are not really design to last to long, or stand up to long term heavy usage. They are built to sell at a low price and getting a worthwhile profit out of producing items for this level ...

Their later model called the C & H Advantage pro is a fabulous example of quality design and engineering. As an ex-engineer I like it very much and it's always been an ambition of mine to own one someday.

As far as I know they should be still available through Nielsen Bainbridge, but dealing directly with the company is like pulling teeth, so I'm guessing that it would probably be easier trying to get one through one of the smaller independant suppliers who already are used to dealing with them.

The fences on the CS88 are quite cleverly adjustable. :D Maybe they weren't tweaked quite right on that example and that would account for the offset insertions. It's not really that much off.... If I was buying the machine, I would want to be sure what was causing the issue before parting with the...

btw2. Newer cartridges don't seem to be as well made as older ones. I had a lot of jamming with new cartridges and had to sand down the fronts to get them to work. I do the same. I had assumed that it was a tolerance issue with the machine, because I had just bought a new machine and never realised...

I would still consider sealing the surface of the fillets with something to block the transfer of acid generated within the fillets to the artwork.

The colour coded wedge cartridges make it very easy to see what size wedges are already loaded in to the machine. Not realising that you've got the wrong size wedges loaded in to the machine mcartridges might ruin the frame. Wedges in cartridges cost more, but some of us have worked out how to reloa...

When I bought my System 4000, back in 2004, I got a friend who had a long wheelbase, high top transit van to transport it for me and we still had trouble getting it into the van. I took four of us to lift it into the van and there was not much room to spare. It's a lot of extra weight to be thinking...

That's not what it is I would expect from a professionally refurbished machine. My guess would be that the recieeer block is badly worn, or misaligned in some way. I would readily admit that this probably does not prevent you from producing adequate joints and once the back is taped up there is noth...

I can't honestly say that I like the idea very much. The fillets are unlikely to allow the pastel to move in a natural way to prevent any cockling from occuring with changes in temperature or humidity. The pastel needs to be allowed to breathe a little and to slightly expand, contract if conditions ...

I still use a CS-88. Great machines!

I don't have any problem cutting 4mm glass. Scoring 4mm glass is no different to normal 2mm glass, it just takes a little extra force to brake it after scoring the glass.

I would quality the use of the 3mm foamboard with the thought that 5mm foamboard might be advisable in cases where the size of the fabric requires something a little more rigid to avoid bowing when laced. A lot depends up on how much tension is created by the lacing.
