Peter, Not sure you could class the Philibuster as a sports model. More like a mini pylon racer. It was fast and fun. Designed by Phil Greeno who along with Alan Mann were friendly rivals in Pylon racing during that era. Remember Alans Manneater?

Excellent quality cowls from Fiberglass Specialties but their shipping costs can be astronomical.

Fiberglass Specialties make superb cowls but when I bought one for a Goldberg Extra the shipping cost was very expensive.

Don, They could be JIS (Japanese industrial standard) heads. Similar to Phillips and Pozi but different enough to give the type of problem you have encountered in the driver not fitting correctly.

Thread: ASP prop driver stuck!

If the collet had grit in the slot it would not have tightened up on the shaft and would have just moved towards the crankcase until it could go no further. Exactly the symptoms you have described.

just "tapping" the puller may not be enough. It may need a hefty whack!

When you do get it apart check that there is nothing e.g. grit of similar dirt in the slot of the collet. This would prevent the collet closing up and gripping the crankshaft. I found this was the problem on a friends Saito (if I remember correctly) which was proving almost impossible to tighten up the prop.

Grant Shapps is the MP for Welwyn Hatfield.

If he's a fellow forumite's MP could I suggest they write/email him? I know he will probably be busy but it might be an "easy fix" for him.

Well said Alan.

I don't think that anything in DavidH's post is correct!

I think you will find the design of Fukushima Daichi was carried out by General Electric (USA) who stipulated that the back up generators must be positioned in the basement area in order to reduce pump operating costs An unusual design stipulation I would have thought!

Those indicators are intended for lane changing. They flash 3 times then stop. Far better than driving behind someone who has changed lanes and forgotten to cancel their indicators.

Paul, Look at Tower Hobbies, among others, to see what is still available overseas. Could it be that Ripmax are just not importing many of OS's range?

Don't disagree John.

Just answering the question asked by the OP.

I do apologise, I thought we where in the argument room.

No you didn't...

I'm sure he did.

Thread: A sticky glassing problem!
31/03/2019 11:59:13

Allan, I have and still do use resin which is well past its "use by date" ( years not just months) with no apparent problems. It's stored in my workshop with no special treatment. The only problem I've ever had (fisheyes) was with some SP113 a number of years ago when Ripmax apparently changed their supplier and manufacturer and ( according to the original manufacturer probably altered the recipe). I would recommend swabbing with Isopropylalcohol in lieu of meths' which can leave a residue (blooming) on the surface. Gentle heating is also a good idea as the problem seems to be on the overlaps where the laminate is marginally thicker.
