Hi guys, (Quick one) Got window surrounds (reveals) coming up in 80-140mm wide in veneered MDF, walnut lipping etc... MT55 rails aren't suited for it, (RHS rips aren't suitable, it's badly glued on natural veneer). Load of machining in situe as windows are old (twisted/bowed), walls aren't straight. My Hilti guide don't fit (5mm too narrow). Checked Screwfix - none in stock (as to buy separately), FFX (delivery by 16'th)... Could I get Bosch one (GKT55), are they really identical? Or push come to shove going to have to get one at £73 (including courier delivery £15) for late Monday/Tuesday morning from fleaBay? Thanks! (Need be delivered Chilworth, Surrey GU4)

Double-sided (carpet) tape from your local hardware matched with any suitable straight-edge: spirit level, offcut etc? Or maybe some hot-melt glue that can be easily reversed with a hot air gun?

Perhaps I'm too tired or didn't come across what's needed. It's two sheets of 20mm (3/4) walnut veneered MDF 1.2x 2.4m (4' x8' feet) , that need to be ripped length ways accurately and no splinters as veneer is PVA glued. Using MT55 with or without guide rail - RHS cuts get splinters, (I use FesT rails). on LHS it sits unevenly and not wide for a clamp. window (inner) sides will need to be re'trimmed (likely "outer" sides too), but edge needs to be perfect for 4 x35mm lipping. The only way I see it is to use proper parallel guide on reverse side, so RHS splinters would be at the back. It's MDF, if I use 48t blade will end up with clogging/burn marks. If you suggested to make the guide, I'd still need the bars (I think 9mm) and it's not going to be very professional to be wasting half a day making it... I'm sure there was a thread about compatibility, if Bosch would fit (and I think it's load cheaper) and I think I can get it delivered from their warehouse (I think near Heathrow or tool shop not that far away)... Sorry, hope, I'm making sense...

Sorry, can't help with compatibility. I have one (parallel guide) with my KSS 50, & haven't even tried it on the MT55!
If splintering &/or burning is a potential issue or probability, maybe you could make your cuts a mm or two wide & follow-up with a trimming pass with a router back to your final cutline?

If splintering &/or burning is a potential issue or probability, maybe you could make your cuts a mm or two wide & follow-up with a trimming pass with a router back to your final cutline? Roughly the plan They'll be all cut to the biggest size +5mm, get in situe, mark only window (varnished type I think that old "plastic injected" wood... ANW 0 gaps) but as I had spirit level they are bowed/twisted, of level, of square), ideally I'd "undercut" 2-3° , bottom line routing would take too long and front, need lip added glued and sanded, before ready made moulding would end nailed on as architrave. TBH most are 1.9 m (narrowest 80mm) would vibrate too much with router anyway and its only 600mm waste in total, that works out to be at most. Definitely need parallel guide and on Monday... and I'm tight as ducks a4se, just can't click on full price with "premium" delivery... And clock is ticking.... 🤪😜 Thanks for good intentions m8, cheers 🍻🥃

"Insult to an injury" 🧐 Bosch guides are equally or more priced as Mafell...
Be it, what it is, placed order for a parallel guide at full price, with guarantee of delivery before 12 on Monday. Better be so or... (I'll moan) 😆

The high price of tools and accessories is quickly forgotten as we find new ways to use them and earn more money.
...as an asides, can't you do the cut from underneath?.. not following your description.

Yes Mafell has "under'tow", unlike FesT on the surface consequences. Yes, the only way dealing with narrow cuts, using guide RAIL or parallel guide is to work out cutting from the back. Still too much of a hassle to calculate (blade thickness, possible break at the back of a cut) with an rail - parallel guide is a must on this one and only one job so far...

I make up jigs to fit on to the parallel guide - means you can have left and right guide - ideal for splitting wood down the middle or grooving for back panels. There are a couple of holes - presumably to take screws. Also handy to fit a piece of sacrificial wood for trimming really close to the edge.

I don't have none parallel guide to start with m8, guide rails worked... That was it. Yes, I'll use "packer" on a saw side, but I need perfect cuts from "uderneeth" on the rather narrow bits of MDF... 😉 I need to have rips to try on all-ready, before, I'll need to trim them bit further.

I might not be following either, but if I get the gist of it then how about sandwiching the veneered mdf between two sheets (12mm or thicker) of sacrificial mdf and cutting through all to get the clean edges you're after?

Yes an NO! I priced the full 6 window job as 5 days work, extra time and extra material would work, but... Let's say 3mm "bow" and 3°of square against the window edge work would mean me loosing money already as it would take me phaffing about too long. And then, I'm limited to what's doable with limited amount of (£120 a sheet) cuts on material, as I'm allowing 8mm on x18, it hardly leaves too much to play with Really hope, I'll have all set up and parallel guide ready on Monday, be it once off needed accessory
